Setting special days or time slots in RadScheduler
HOW TO
Set special days or times slots in RadScheduler.
DESCRIPTION
Two special days are defined in code-behind - June 26 and 27. In the TimeSlotCreated event handler the CssClass property is set for each time slot within the special days boundaries to visually distinguish the special days.
Note, that the special days functionality is achieved using time slots which meet certain criteria. You are not limitted to whole days only. You can set special time slots, for example - highlight the time slot for the current System Time.
SOLUTION
<style type="text/css">
.Disabled
{
background: silver !important;
cursor: not-allowed;
}
.Disabled.rsAptCreate
{
background: silver !important;
}
</style>
<script type="text/javascript">
//Cancel OnClientAppointmentInserting if a time slot in a special day is double-clicked(insert is attempted).
function OnClientAppointmentInserting(sender, eventArgs) {
var slotElement = $telerik.$(eventArgs.get_targetSlot().get_domElement());
if (slotElement.is(".Disabled") || slotElement.parent().is(".Disabled")) {
// Prevent appointment inserting on holidays.
eventArgs.set_cancel(true);
}
}
//Disable context menu for special slots if it is enabled
function pageLoad() {
$telerik.$(".Disabled").bind("contextmenu", function (e) {
return false;
});
}
</script>
<telerik:RadScheduler ID="RadScheduler1" runat="server" OnClientAppointmentInserting="OnClientAppointmentInserting"
SelectedView="WeekView" OnTimeSlotCreated="RadScheduler1_TimeSlotCreated" OnAppointmentUpdate="RadScheduler1_AppointmentUpdate"
SelectedDate="2008-06-26" OnAppointmentDataBound="RadScheduler1_AppointmentDataBound">
<TimeSlotContextMenuSettings EnableDefault="true" />
</telerik:RadScheduler>//Set your special days here:
private readonly DateTime[] SpecialDays = new DateTime[] { new DateTime(2008, 6, 26), new DateTime(2008, 6, 27) };
protected void RadScheduler1_TimeSlotCreated(object sender, Telerik.Web.UI.TimeSlotCreatedEventArgs e)
{
foreach (DateTime dt in SpecialDays)
{
if (DateTime.Compare(e.TimeSlot.Start.Date, dt) == 0)
{
//Set the CssClass property to visually distinguish your special days.
e.TimeSlot.CssClass = "Disabled";
}
}
}
protected void RadScheduler1_AppointmentUpdate(object sender, Telerik.Web.UI.AppointmentUpdateEventArgs e)
{
foreach (DateTime dt in SpecialDays)
{
if ((DateTime.Compare(e.ModifiedAppointment.Start.Date, dt) == 0) || (DateTime.Compare(e.ModifiedAppointment.End.Date, dt) == 0))
{
e.Cancel = true;
ScriptManager.RegisterStartupScript(Page, GetType(), "alert", "alert('The duration of appointment contains Special Days!');", true);
}
}
}If you already have an appointment with duration containing the Special Days - you'll need to disable the editing and deleting of this appointment as it is in the category of "disabled". To achieve this you'll need to subscribe to the OnAppointmentDataBound event and use this code:
protected void RadScheduler1_AppointmentDataBound(object sender, SchedulerEventArgs e)
{
foreach (DateTime dt in SpecialDays)
{
if ((DateTime.Compare(e.Appointment.Start.Date, dt) == 0) || (DateTime.Compare(e.Appointment.End.Date, dt) == 0))
{
e.Appointment.AllowDelete = false;
e.Appointment.AllowEdit = false;
}
}
}VARIATIONS
Set special days or time slots which meet certain criteria. For example, if you don't know in advance the special dates and you need to disable days which don't have any appointments, then modify the code from the attached project as follows:
private List<DateTime> SpecialDays = new List<DateTime>();
protected void RadScheduler1_TimeSlotCreated(object sender, Telerik.Web.UI.TimeSlotCreatedEventArgs e)
{
//Check if there are any appointments for the current time slot date:
if (RadScheduler1.Appointments.GetAppointmentsInRange(e.TimeSlot.Start.Date, e.TimeSlot.Start.Date.AddDays(1)).Count > 0)
{
//add this date to the SpecialDays collection
SpecialDays.Add(e.TimeSlot.Start.Date);
//set your custom css class
e.TimeSlot.CssClass = "HasAppointmentsClass";
}
else
{
e.TimeSlot.CssClass = "Disabled";
}
} Private SpecialDays As New List(Of DateTime)()
Protected Sub RadScheduler1_TimeSlotCreated(sender As Object, e As Telerik.Web.UI.TimeSlotCreatedEventArgs)
'Check if there are any appointments for the current time slot date:
If RadScheduler1.Appointments.GetAppointmentsInRange(e.TimeSlot.Start.[Date], e.TimeSlot.Start.[Date].AddDays(1)).Count > 0 Then
SpecialDays.Add(e.TimeSlot.Start.[Date])
e.TimeSlot.CssClass = "HasAppointmentsClass"
Else
e.TimeSlot.CssClass = "Disabled"
End If
End SubHighlight the current day.
protected void RadScheduler1_TimeSlotCreated(object sender, Telerik.Web.UI.TimeSlotCreatedEventArgs e)
{
if (DateTime.Compare(e.TimeSlot.Start.Date, DateTime.Now.Date) == 0)
{
e.TimeSlot.CssClass = "CurrentDayStyle";
}
} Protected Sub RadScheduler1_TimeSlotCreated(sender As Object, e As Telerik.Web.UI.TimeSlotCreatedEventArgs)
If DateTime.Compare(e.TimeSlot.Start.[Date], DateTime.Now.[Date]) = 0 Then
e.TimeSlot.CssClass = "CurrentDayStyle"
End If
End Sub Hightlight the current time slot.
protected void RadScheduler1_TimeSlotCreated(object sender, Telerik.Web.UI.TimeSlotCreatedEventArgs e)
{
if ((DateTime.Compare(e.TimeSlot.Start.Date, DateTime.Now.Date)==0)&(e.TimeSlot.Start.Hour == DateTime.Now.Hour))
{
e.TimeSlot.CssClass = "CurrentTimeSlotStyle";
}
